Method and device for realizing network interface of multimode terminal and data card

Abstract

The invention relates to the field of communication, and particularly relates to a method and a device for realizing a network interface of a multimode terminal and a data card, so as to solve the problem that a network port and a modem port are respectively required to be developed for an existing multimode terminal so as to meet access of different networks and the network connection modes are different due to different accessed networks, so that the network accessing operation is complex. According to the embodiment of the invention, an LTE (Long Term Evolution) module in the data card is adopted for receiving first information, which is required to be sent to a base station, of the terminal by virtue of a communication interface; the LTE module is used for determining second information according to the first information after determining that the first information is 3G network information, and then transmitting the second information to a 3G module in the data card by virtue of a 3G communication interface; the 3G module is used for uploading the second information to a 3G base station, so that development of the modem port is not required to be performed on the terminal, information of different network types can be sent out by virtue of one network interface, so that switching among the different networks is more stable.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for realizing a network interface of a multi-mode terminal data card. Background technique [0002] A communication system is a facility that supports communication between multiple devices, and users access communication devices to the communication system through a suitable communication network. At present, the main communication networks include the long-term evolution project LTE (LongTermEvolution) network and the third-generation mobile communication technology 3G (3rd-generation) network. Users operate according to a given communication network standard or through a given specification to realize different communication networks. both integrated. [0003] In order to enable users to choose different networks according to the quality of the current network, the user terminal needs to adopt a multi-mode mode, that is, the user terminal selects the correspondin...

Problems solved by technology

[0005] Embodiments of the present invention provide a method and device for implementing a network interface of a multi-mode terminal and a data card to solve the problem that the current multi-mode terminal needs to develop network ports and modem ports separately to meet the access of different networks. The wireless communication interface switches between different networks, the network stability is poor, and the connected networks are different, the network connection methods are also different, and the operation of connecting to the network is cumbersome.
